Application ledll'uly 6, 1926'.` Serial No. 120,768.

The invention relates to machines `for per torating clamping lugs attached to tire carry.- ing rims. One ot the objects of the invention is to prov'idethe` machine with means for mechanically positioning the` rim to` locate the lugs tor engagement withfthe perforating punches. Another object is to provide ama? chine with `means for shrinking a transversely split `rim to size the same and assist in locatfiu ing the lugs for engagemcntwith the perL torating punches. Further objects `of the inventionreside in the novel features of con-A struction andcombinations and arrangements of parts as more fully hereinafter: set forth.A

In the drawings Figure l is .a plan view, partly` in section, ot' a` machine embodying my invention;

Figures2,3,.4 and are-crosssections, respectively, on4 the linesQf-Q, 3.f3,.4-4 and5--5 of Figure 1.

The machine embodying my invention. isA

designed fon use in perforating clampinglugs which are permanently` attached .to tire `:carrying rims and particularly tire carrying rims of the transversely split` demountable type. L is the rim which: is transversely split str2, and 3 are the clampinglugs.; These lugs are permanentlyv attached tothe rim'in` ai solidi` or imperiorate stateandmy machineisldesigned ltoperforate these lugs thereby providing` bolti holes.

The machine is in the nature ofa press and. has the shoe et which is suitably securedlto `the bolsterplate or; bedand the holder. 5 located towardiand away` from the samethis,holder= being adapted to be secured to the rim` Forsizing the rim, Ihave providedithe shrinking blocks 6 which are slidably mounted upon the shoe itand surround the rim.. These shrink? ing blocks are movable radially inward to i engage the rimandshrink the same to size as;

well astoshape the same.` 7 i are cams which are secured toand depend from theholden 5 andare engageable with the rolls 8` carried b f by' the shoe 4i to iforce the shrinkingsblocks radially inward `.upon downward movementzof the holder. These shrinkingblocks are. yield` the holder 5 and cam 7 are in their upper positions the shrinking blocks are `disengaged from the rim. As shown, every. other shrink` ingblock is yieldably forced outwardlyfby means of the coil spring 10 having its `inner above the shoe and: vertically. ieciprocable,y

the shrinking blocks and the rolls 9` carried:

ably forced radially outwards() that when .i

endahuttingA the blockll audits outer endl abutting the projection 12gof the shrinking` block, which projection extends radially inward below the rim. Each of the interme-` diate shrinking blocks is` yieldably forced? outwardly by means of the coil springs ltr` having their inner ends abutting the bloclii'll` and; their outer-ends abutting the plungersi 14` which in turn abut thehifurcationsw15.` formedupon these alternate shrinkingrblonks and `extending radially inward below the rim. i. The `block 11 is mounted upon andzseeuredlto the shoe 4 within the shrinking blocks 6J The` projections 12 andthe bifurcations 15 of the shrinking blocks are located to supportthe" rim which is inserted intoLthe machine with its outer edge lower-most;

For positioning the rim with its attached lugs to locate thelatter forengagementhy` the perforating punches, I have provided the 'l5 reciprocable bar 16` which isradially slidable. inthe block `11 and normally @forced outward* ly to engage between the endsof the rim by` the coil spring 17. Theputerend. of this bar is rounded so `ithat: Whenthe `rinnis being` contractedits ends` cooperate to `force the bari radially inwardbeyond the rim so `that these ends may Contact. Iralso provide the posi tioningplungerlB `which is engageablein thei valvehole ofthe rim. This plunger is ra1- dially slidable inthe `block-11 and` ituis com nected at its inner` endby means of the `pin 19to one end ofthe lever 20, theyotherend of this lever being connected'to the blockl 11.` by the pivotl. 221 is a coilspring located within the block 11 and extendingradially and 23 is a headed` plunger which is forced? against the outer side ofthe lever 20 bymeansf of this coilfspring to thereby normally hold" the plunger 18 radially inward and away' from the rim. For-forcing this plunger into` the valve stem holethere is the plui1ger24` which is radially slidahle inrthe blockf111 and. has its outer endengageable withlthe inner: side of the leverQ() opposite thc headed plung- 100 en 23.. rIlhis plunger 24 `has its inner end en'- i gageablewith the cam 25 which isri "dl w secured iat the side `ot' the block126, thislocl;` depending centrally4 from the holder` 5 and being rigidly secured thereto.

Forwclainping the lugs afterL the rimihas been successivelyipositionedand sized, I have provided foreach-.lug thedie 27v wliiohiis mountedeupontheiblockll andis located to engage the outer` face of the lug andthe clamp 11,0y

rllhis holder block is vertically slidable upon the holder block and is normally forced downwardly awa-y from the holder by means of the coil spring 30 having its upper' end almtting1 the holder and its lower end abutting the cam, the arrangement being such that the clamp 28 is yieldably torced outwardly and down-A' wardly to Contact with the lug and clamp the same in place so that variations in thickness of the lug may occur without danger oit breaking the parts ot the machine. Each clamp 28 is normally forced radially inward so that it will not interfere with the insertion or removal ot the rim with its attached lugs. as by means ot the coil spring 3l which is lo cated in a recess in thc block ll below the clamp and has its outer end abuttin .he end ot the recess and its inner ond abutting the pin 32 which is secured to the clamp.

33 are punches carried by the punch holders 34 which in turn are carried by the holder 5, there being one punch tor each lug. rllliesc punches are ongageable with the lugs to per-- forate 'the same alter the latter have been clamped in place.

ln operation and assuming the holder 5 to be in its uppermostposition, the shrinking blocks 6 to be in their radially outward positions and the positioning bar 16 to be in its radially outward position a rim l with imperiorate attached lugs is placed in the machine on edge and with the lugs lowermost, the rim ends being on opposite sides ot the bar 16. The holder is then lowered carrying with it the cams 7, the central block 2G.` the cam 25 and the punches 33 and also yieldably carrying the cams 29 downwardly. The cams 7 operate to move the shrinking blocks G radially inward and during this radial inward movement of the shrinking' blocks the cam 25 operates to more the positioning plunger 18 radially outward into the valve hole of the rim. During the radial. inward movement oit the shrinking blocks the ends et the rim 'force the positioning bar 16 from therebetween. After the rim has been shrunk to size tl c cams 29 operate upon the clamps 28 to yieldably force the same outwardly and downwardly to clamp the lugs upon the dies 271 ai'ter which the punches come into engagement with the lugs and pertorate the same. The holder then rises and the various parts assume their original positions when the rim may be removed and replaced by another.
